23mm*8mm 60-Degree 93% Transmittance Glass Optics (2-Pack)

Pros: Inexpensive.
Fairly good quality, good enough for flash light.

Cons: One of them I received hade a small scratch on the side.

Other: Very nice.

Pros: Super wide lens. Can evenly distribute light evenly and sharp cut off. Very round lens, has a huge convex to the front

Cons: Small scratch, but its unnoticeable. Too thick for the base, didn't fit perfectly on my flashlight.

Other: Buy it. I have this custom installed on my C6-T60 Ultrafire. Super wide light and extremely bright. Very useful afterwards because of the super wide light. Ex: see in images

Pros: I use these lens with my 10w leds with 170 degrees when I add the lens to reduce 90 or less I guess, now the light is more bright focused, the transmittance of light through the glass is clear, very sharp, I'm happy with the purcharse, I'll buy again for sure!!!!!!!!!!!!!!!!!!!!!

Cons: the package dosn't come with protection (comes in a plastic bag wrapped with paper, so maybe could be chipped the glass, other thought none for the moment.......-

Other: none

Pros: - Inexpensive - Great replacement for plastic lens that my flashlight had - Theres 2 of them

Cons: The lip around the edge was a little to thin for my flashlight, but a piece of 3m blue tack fixed that... not really a con of this product, just a con with my application.

Other: Works great as a replacement for the plastic dome lens that those "zoom to throw" (sku.39585) have.
